WHEEL-GUARD;

Applicationifiled April 7, 1919/ Serial no, 287,935.

To all whom it may concern: 7 Be it known that I, W'ALTER H. SMITH, subject of the King'of Great Britain, residing at Pittsburgh, in the. county of Allegheny and State of Pennsylvania, have invent-ed certain new and useful Improvemen-ts in VVheel-Guards, of which the following is a specification.

This invention relates'to a wheel guard, and com-prehend-s a structure which may be placed against the spokes of a fly wheel or the like to cover the space within the rim of the wheel and readily and conveniently secured in such position.

It has been heretoforeproposed to apply guards of this character to spoke wheels to prevent the possibility of accidents incident to the rapidly moving spokes, but such guards have been secured in position ordinarily by means passing through thespokes,

with the resultant weakening of the wheels, and have usually beeneonstructed of heavy material, such as metal plate.

This invention is directed particularly therefore to the provision of an improved guard having simple and efficient means by which it may be readily and easlly secured to or removed from an operative position relative to the wheel.

In the drawings Figure 1 is a view in elevation from the inner side showing the improved guard in position- 7 Fig. 2 is a section on line 22 ofFig. 1, with the parts in position immediately preceding the completing of the secure opera tion.

. Fig. 3 is a similar view with parts in guard securing positions. 7 i

Fig. i is a detail perspective.

In the drawings, a fly wheel is indicated at 10, having the usual spokes 11 and 12. A guard 13 is provided,,and of a diameter to it more or less closely within the rim of the wheel, so that it may bear directly against the spokes. The guard is of three ply construction, the center portion 14 being of wood, and the outer plys 15, being of card board, fiber, or other appropriate material.

The guard is formed at thecenter with an opening 16 topermit the guard to be passed over the hub of the wheel.

The fastening means comprises strips 17,

of bendable metal, riveted ,at theirinterme diate points, as at 18, to the guard, to leave 7 particular construction of the to cooperate with the said clips, the'bend- Specification of I etters Patent. Patented Feb, 3,192(),

free ends length.

spoke, by preference, though obviously the invention contemplates a less number if de' sired. 1

19 of such strips of appropriate 7 There. 1s one such strip for each her, as shown in Fig. 3. The guard is thus I effectively secured to the spokes, and will efiiciently prevent the danger incident to contact with thespokes of the rapidly revolving wheel. 7

In removing theguard it is only necessary to bend outwardly the free ends ofthe strips, andreniove'the members 20. .The securing m us provides f r convenient storage or transportation of the guards, as under such conditions the strips willlie flat against the inner surface of'the guard and present no appreciable addition to the thickness thereof.

There is considerable advantage in the construction of the guard portion of wood faced at eachside with card-board, fiber or the like. Wood alone would be liable to split and flyapart under the action of com trifugal force. By the addition of the cardboard .facings, this possibili is eliminated, and a guard portion is provided which is light in weight, cheap, strong, safe, and silent in use.

What I claim is I V I 1. The combination with a fly wheel having spokes,,of a guard adapted to be positioned against the spokes, clips carried by the guard to embrace the spokes said clips having bendable ends and a holding member able endsbeing bent around said holding means.

The combination with a fly wheel having spokes, of a guard adapted to be positioned against the spokes, clips carried by the guard to project on opposite sides of the spokes saidclips having bendable ends and a member adapted to bear against the spokes on the side opposite the guard and tobe; interlocked with said clips by bend-- ing the ends of the latter around the;mem-

is ber.

3. A wheel guard comprising" a guard member, strips secured intermediate their ends to the member and adapted to be bent outwardly from the Spokes betweenthem,,and a holding member interlocked with the ends ofsaid strips be yond the spokes.

4. The combination with a fly wheel having spokes, of a guard of three-ply material adapted to lie against the spokes and having U-shape memberssecured thereto to receive the spokes, and a ring-like lock adapted to embrace the free ends of the members beyond the spokes, the ends of said members therewith,

guard to receive the like lock'adaptedto embrace the'free ends of the membersbeyond the spokes, the ends 7 of said'members being bent around the lock to secure therguard in position.

6. A' wheel guard comprising a guard member and Ineanslor securing the guard member to the spokes of wheel including two elements one of said elements having bendable ends to be bent around the'other element to form a lock.
